Problem & impact

Refineries, chemical plants and substations still rely on a patchwork of generic MCU nodes, discrete gas detectors and separate vibration or acoustic sensors.

  • Gas detectors are often far from the actual leak – alarms trigger late or not at all.
  • False alarms and nuisance trips lead to alarm fatigue and raised thresholds.
  • Generic MCUs running TinyML in software burn too much energy per inference, limiting sampling rates and analytics richness.

GuardianEdge aims to:

  • Enable earlier detection of leaks and anomalies using fused gas + acoustic + vibration features.
  • Support dense deployment of battery-powered nodes with multi-year coin-cell lifetime.
  • Reduce unplanned downtime and maintenance truck-rolls while improving worker safety.

Solution – GuardianEdge SoC

GuardianEdge is a domain-specific multimodal sensing SoC that integrates:

  • Configurable analog front-ends for gas and environmental sensors.
  • Acoustic/vibration front-ends for machine and infrastructure monitoring.
  • Fixed-point digital front-ends, feature extraction and a TinyML/rule engine.
  • A deeply event-driven power and clock-management state machine.

The SoC is radio-agnostic and connects cleanly to sub-GHz, NB-IoT/LTE-M, Wi-Fi or 5G modems.

In our current MATLAB/Simulink proof-of-concept, gas and acoustic signals are processed through dedicated digital front-ends (Gas_DFE and Acoustic_DFE). Each channel computes a severity level; a fusion engine combines them into a fused severity and a critical_alert signal, which drives the future hardware power FSM and alert outputs.

Technology & verification

Core technology

  • MATLAB/Simulink models for gas and acoustic channels, including synthetic leak profiles and machine noise.
  • Fixed-point digital front-ends designed to map cleanly to HDL (Gas_DFE, Acoustic_DFE).
  • Multimodal fusion logic with tunable thresholds and severity levels.
  • Architecture designed for separate always-on and active domains for deep event-driven operation.

Verification & safety roadmap

  • Planned UVM-based, constrained-random and coverage-driven verification at SoC/IP level.
  • Functional & code coverage plus assertion-based verification of key safety properties.
  • Design-for-test: scan insertion, memory and logic BIST, analog loopbacks.
  • Architected to support IEC 61508 / ISO 13849 system-level safety, with EMC and cybersecurity standards (IEC 61010 / 61326 / 62443) and secure boot / hardware root-of-trust on the roadmap.

Business model & target customers

Platform business model

  • SoC & IP – GuardianEdge SoC sales; licensing key IP blocks such as AFE, DSP and power manager to MCU/SoC vendors.
  • Modules & reference designs – pluggable sensing modules for OEMs and system integrators.
  • Software / SDK / services – configuration tools, TinyML deployment and design-in support for key accounts.

Target customers

  • Industrial gas and safety detection OEMs.
  • Predictive maintenance and condition-monitoring vendors.
  • Energy and infrastructure operators (substations, pipelines, storage).
  • Building automation and industrial system integrators.

Future features – 5G/6G & ISAC

Short term – 5G/IoT-ready endpoint

  • GuardianEdge acts as a radio-agnostic sensing endpoint behind sub-GHz, NB-IoT/LTE-M, Wi-Fi or 5G modems.
  • Nodes transmit compact multimodal feature vectors rather than raw signals.
  • Edge and cloud platforms perform higher-level ISAC analytics and digital twin modelling.

Long term – integrated sensing and communication

  • Add ISAC-DSP blocks to ingest RF features (e.g. channel state information) from 5G/6G radios.
  • Fuse RF with gas/acoustic/vibration data for occupancy mapping and dynamic safety zones.
  • Vision: GuardianEdge becomes the multimodal sensing backbone for 5G/6G-enabled factories and critical infrastructure.
